The Great Emergency (not)

So last night my sister (Kayla) brother (Cooper) were watching a movie while mom and dad were out at dinner the smoke alarm started going off.We thought it was the carbon monoxide alarm so we ran as fast as we could out the door and into the driveway.After a brief council we decided to go over to our neighbor's house and knocked on her door.She was shocked and let us in.Then she called 911 and the firetruck came to check it out.They didn't find anything of harm and told us we could go back to our house.After the firemen left we went back to our house and called our mom and dad.Dad was so amazed, they were home in a very short time.A friend of ours drove by and called my dad and asked why their was a firetruck in front of our house while they were at the dinner.My dad called him back and said "get buckets and get over here now!" But the fireman did say our fireplace was unsafe and it was made for a wood stove and was a bad fireplace.That was probably the cause of the alarm going off.So we won't be lighting many fires any more.You see why I called it The Great Emergency (Not)!!
